21.5 If the ridge cap detail is to be used, place the inside ridge cap and caulking bead as shown on the shop drawings. The caulking bead

should be married to the bead in the overlapping ribs as the panels are set in place.

21.6 Roof panels that incorporate the laps will arrive at the jobsite with the foam and liner face in place. The liner face of the upper course

panel will have a factory saw cut 3" to 6" from the end of the panel (see figure 16, below). Remove the metal and foam at the end of the

panel. Carefully remove any foam that remain on the metal skin to ensure a positive air and water infiltration seal.

21.7 After preparing the upper course panel, placing the caulk, set the upper course panel in place. Install saddle washer assemblies on all

supports.

21.8 Once the upper panel is in place and fastened, fasten down the end-lap using the 1/4 - 14 x 7/8" stitch fasteners. The fasteners should

be placed in the locations shown on the all weather insulated panels shop drawings. The fastener should be placed approximately 1"

from the end of the upper course panel exterior facing so that it penetrates the caulking and achieves full compression of the facings at

the last row of caulking.

21.9 Remove all metal chips and filings from the drilling of pilot holes and fastening of the panels immediately after installation. These filings

will rust and corrode the panel surface.

21.10 Proceed to the next panel and repeat steps 13.2 through 13.9.

21.11 After all panels are installed fasten the eave, rake, and peak trims, respectively. The trim should be fastened as shown on the shop

drawings.

22.0 PEAK TRIM INSTALLATION PROCEDURE

22.1 Fasten the roof panels at the ridge as shown on the shop drawings.

22.2 Temporarily set the Peak trim in place to determine the location of the caulking and closure strips. Run a line or snap a chalk line along

the length of the Peak trim for proper placement of the caulking and closure strips.

22.3 Apply butyl tape onto the panel as shown on shop drawings in preparation for the closure strip. All surfaces to receive caulk and closure

strips.

22.4 Seat the closure strip firmly onto the butyl tape to ensure a continuous seal. If voids exist, add additional butyl sealant and reseat the

closure correctly.

22.5 Place butyl tape onto the closure strip and place the Peak trim as shown on all weather insulated panels shop drawings. Fasten the Peak

trim at each hi rib with a 1/4- 14 x 7/8" stitch fastener. At the end of the apex trim, place two beads of the caulk or tape sealant 2" from

the end and overlap the next Peak trim approximately 4". Fasten the overlaps down with 1/4 - 14 x 7/8" stitch fasteners as required.

22.6 Immediately remove any metal chips or filings from the screws or sheet metal fabrication as they will rust and corrode the panel surface.
